Negative net cash may be the result of a variety of factors including, but not limited to, (1) pending receivables or (2) amounts owed to the fund due to balancing amounts with respect to purchases and redemptions of creation units, but is not the result of the use of leverage.

1. Index Reconstitution -- March 12, 2018
Indices are rebalanced and reconstituted on a quarterly basis. The next reconstitution will be implemented after the close of trading on March 16, 2018, as set forth in the link below.
Access Index Reconstitution.

2. Special Risks: An investment in the Fund is subject to investment risk, including the possible loss of principal amount invested. Fund returns may not match the return of its respective index, known as non-correlation risk, due to operating expenses incurred by the Fund. The alternate weighting approach employed by the Fund (i.e., using revenues as a weighting measure), while designed to enhance potential returns, may not produce the desired results. Because the Fund is rebalanced quarterly, portfolio turnover may exceed 100%. The greater the portfolio turnover, the greater the transaction costs, which could have an adverse effect on Fund performance.

4. Holdings are subject to change, and are dollar weighted based on total net assets.

5. Negative net cash may be the result of a variety of factors including, but not limited to, (1) pending receivables or (2) amounts owed to the fund due to balancing amounts with respect to purchases and redemptions of creation units, but is not the result of the use of leverage.

6. Standardized yield is based on an SEC standardized formula designed to approximate a Fund's annualized hypothetical current income from securities less expenses for the 30-day period ending and including the most recent month-end or quarter-end and that date's NAV.

A. Daily net asset value and dollar change of the fund is as of the previous business day's closing. Fund net asset values are updated at approximately 7:00pm ET daily.↩

B. The performance data quoted represents past performance, which does not guarantee future results. The investment return and principal value of an investment in the Fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Current performance and expense ratios may be lower or higher than the data quoted. Returns do not consider capital gains or income taxes on an individual's investment.

The NAV return is based on the net asset value of the Fund and the market return (MKT) is based on the market price per share of the Fund. The price used to calculate MKT is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which the shares of the Fund are listed for trading when the Fund's NAV is calculated at market close. MKT and NAV assume dividends and capital gain distributions have been reinvested in the Fund at market price and NAV, respectively. Returns less than one year are cumulative.

"Year to Date" returns are cumulative, not annualized, and do not reflect sales charges (if sales charges are applicable to the Fund). These returns would be lower if sales charges were taken into consideration. Short-term returns may not be indicative of longer-term performance, which should also be considered when making investment decisions.↩

C. The performance data quoted represents past performance, which does not guarantee future results. The investment return and principal value of an investment in the Fund will fluctuate so that an investor's shares, when redeemed, may be worth more or less than the original cost. Current performance and expense ratios may be lower or higher than the data quoted. Returns do not consider capital gains or income taxes on an individual's investment.

On 2/22/2008 and 3/31/2008 for RWL, the last trade price was used to calculate market return because 4:00pm EST midpoint bid/ask prices are not available on those dates. On 9/30/2008, the last trade price for RWL was used to calculate market return because an uncorrected, failed trade resulted in an incorrect 4:00pm EST midpoint bid/ask price on that date.

The NAV return is based on the net asset value of the Fund and the market return (MKT) is based on the market price per share of the Fund. The price used to calculate MKT is determined by using the midpoint between the highest bid and the lowest offer on the primary stock exchange on which the shares of the Fund are listed for trading when the Fund's NAV is calculated at market close. MKT and NAV assume dividends and capital gain distributions have been reinvested in the Fund at market price and NAV, respectively. Returns less than one year are cumulative.

"Year to Date" returns are cumulative, not annualized, and do not reflect sales charges (if sales charges are applicable to the Fund). These returns would be lower if sales charges were taken into consideration. Short-term returns may not be indicative of longer-term performance, which should also be considered when making investment decisions.

Returns are preliminary and subject to change until the first business day of the month.
